Abstract
AbstractThis paper consider usefulness of modeling of radio–control car (RC–car) for visual feedback system by closed–loop identification. For a plant which is the RC–car with camera, steering signal is an input and feature point on image is an output. This research goal is to design a model for visual feedback controller. The RC–car runs not only on straight but curve. For this reason, we need to measure output data on curve driving with random input in order to design the curve model using input and output data sets. Modeling based on system identification has to use the random input, the driving of RC–car with random input is however difficult. It is necessary to get input-output data with controller. Therefore, we have to use a closed–loop identification for taking data of identification. In this paper, we make a model of RC–car by open-loop and closed–loop identifications and we investigate reasonability.
